You can upgrade the generator to one of 40 or 45 amps out, if lacking power. These are common in the late '40-early 50s.
A local electric shop may also be able to rewind yours for more output.
Fan speed is proportional to power draw, so the slower it turns the less amp draw by power of 3. If available in 6V, consider a thermostatic or two/variable speed unit for less draw when not needed.
I assume you've checked your temperature measurement, all the front air deflecting sheet metal is intact, and '39 is not the thermostatic louver year.
